How many phases are there in TCCC?

Tactical Combat Casualty Care (TCCC) is structured around three distinct phases that guide medical personnel in providing care in combat situations. The correct answer reflects the comprehensive framework established to address and prioritize the management of casualties effectively.

The three phases of TCCC are:

1. Care Under Fire: This initial phase focuses on performing life-saving interventions while still under enemy fire. It emphasizes safety and the immediate control of life-threatening hemorrhage.

2. Tactical Field Care: This phase occurs once the casualty is safe from the threat of enemy fire. It permits a more thorough assessment and treatment of injuries without the pressing danger of attack.

3. Tactical Evacuation Care: This final phase involves treatment during the evacuation process, whether by ground or air transport, ensuring the casualty continues to receive appropriate medical care until they reach a higher level of medical facility.

Understanding the rationale behind these phases is crucial for effective training and implementation, which is why the answer of three phases is correct. The other numbers do not align with the established TCCC framework, which is specifically designed to enhance the effectiveness of trauma care in combat situations.
